This examination paper is about the potential for Solar cells on apartment blocks. The technology with using solar cells for manufacturing electricity, has been on the market for a while, but recently the new installations of solar cells has increased. Solar cells are suited for placements on buildings but are expensive to obtain. The municipal real-estate company is interested in solar cells but wants to know more before they invest in the technology. This report contains an account of the solar cell and a guide to how a connection to the grid is accomplished.

This thesis focuses on Chinese?Swedish code-switching of bilingual children in Sweden. The purpose is to, through a case study, study what Chinese?Swedish code-switching looks like in daily conversations between bilingual children and their parents. Three main questions are formulated from the purpose of the thesis, foucusing on the types and frequencies of code-switching, the grammar of code-switching, and the motivation of code-switching.The linguistic material comes from voice recordings of naturally occurring conversations between three children and their parents, which are transcribed afterwards.

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..

Uppsatsen har undersökt hur ett antal textbaserade utbildningsmaterial avsedda för utbildning inom företagsvärlden utformas i förhållande till olika sätt att förstå och tolka innehåll. De teorier som används som utgångspunkt i undersökningen har varit Howard Gardners inlärningsteori om multipla intelligenser, samt Stuart Halls kommunikationsteori Encoding/decoding. Undersökningen har omfattat tre utbildningsmaterial som används vid Södra Cell Mönsterås som tillverkar pappersmassa, där jag undersökt en teoribok avsedd för utbildning av truckförare, en internhandbok i grundläggande datakunskap samt ett textmaterial avsett för att öka personalens kunskap om hur produktionen av pappersmassa går till. Undersökningen har gjorts i form av fallstudier där varje utbildningsmaterial har blivit ett separat fall. Analysen av materialen har genomförts i form av en riktad innehållsanalys baserad på Gardners multipla intelligenser, i syfte att finna svar på vilka intelligenser som var representerade i utbildningsmaterialet. Utifrån det resultat som analysen gav förde jag ett hermeneutiskt teorietiskt resonemang med utgångspunkt i Halls teori Encodin/decoding i hur brukarna av materialet skulle kunna tolka innehållet, beroende på faktorer som förkunskaper i ämnet och kulturell/social bakgrund. Resultatet av analysen visa att endast ett fåtal intelligenser blev representerade i de olika materialen.

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

The aim with our study has been to examine how preschool-staffs resonate about the notification requirements according to Chapter 14, section 1, The Social Services Act, when a child fare badly or is suspected to fare badly: first, in relation to the municipality´s policies, but also in relation to the preschool staff´s actions in individual cases. Our study was conducted by qualitative research with semi-structured interviews. Total has two child´s nurses and six preschool-teachers, active within Växjö´s municipality, been interviewed. The result showed that the municipality´s guidelines on the one hand, underpinned by giving a prescribed pattern of behavior for preschool staff on how to act if the suspected that a child to fare badly. On the other hand preschool staff also experienced the guidelines diffuse as there were nothing described of the transition of how much they should document and observe before a notification could be initiated to the headmaster.

Tall (Pinus sylvestris L.) är ett av Sveriges viktigaste trädslag. Med ökad efterfrågan på vedråvara samt ökade krav på naturavsättningar är det viktigt att öka produktionen i skogen. Röjning och tidig gödsling ger ökad volymproduktion men kan ge icke önskvärd påverkan på vedegenskaper som ökad mikrofibrillvinkel (MFV). MFV är vinkeln mellan mikrofibrillerna i cellväggens S2-lager och cellens längdaxel och påverkas av ståndort samt konkurrensen om ljus och näringsämnen. Höga MFV resulterar i sämre kvalitet på papper och sågade trävaror.

Background: Obesity has expanded to a nationwide issue that affects millions of people. The healthcare system struggles to handle the epidemic as the problem grows. Studies show that healthcare workers have negative attitudes toward obese and overweight people and that they lack knowledge and proper tools to support this patient group. Motivational interviewing (MI) is a known technique for initiating lifestyle changes with patients. Aim: The aim is to evaluate the effectiveness of MI as a tool for weight loss and sustainable lifestyle changes for people with obesity and overweight. Method: This study uses a literature review methodology with a systematic perspective. Data is gathered and analyzed to investigate how MI affects weight loss.

This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..

A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

Fortum har i samarbete med Stockholms stad presenterat en gemensam vision för att göra Stockholm till en av världens främsta miljöbilsstäder till 2030. Ett viktigt led i detta mål är introduktionen av nya elfordon innehållande litium?jontekniken på den svenska bilmarknaden. Då det befintliga regelverket angående laddning av ackumulatorer i fordon inte nämner den nya tekniken har frågeställningen kring luckor i lagstiftningen lyfts fram av Fortum. Det övergripande syftet med studien har varit att undersöka risker och regelverk kring laddning av elbilar innehållande litium?jonackumulatorer.

Syfte: Identifiera recidivmönster hos glioblastom samt studera betydelsen av erhållen stråldos beträffande uppkomsten av recidiv.Metod: 50 patienter som strålbehandlats för glioblastom valdes ut till studien och deras magnetkamerabilder från uppföljningen jämfördes med behandlingsplanen frånstrålbehandlingen. Lokala, marginella eller distala recidiv identifierades baserat på om recidivet låg innanför, tangerade eller låg helt utanför PTV (planning target volume). De marginella delades in i två grupper, de som hade en fysisk koppling, connex, till GTV (gross tumor volume) och de som inte hade det. Vidare lästes erhållen stråldos i recidivet ut från strålbehandlingsplanen.Resultat: 35 stycken patienter hade fått recidiv på 42 unika lokaler. Av dess 42 recidiv var 66,7 % (28 stycken) lokala, 9,5 % (4 stycken) marginella med connex till GTV, 19 % (8 stycken) marginella utan connex till GTV och slutligen 4,8 % (2 stycken) distala.
